Since your main goal is to grow a stronger network, considering US universities is of no use. However, if you are okay with developing international networks US universities are a viable option. 

Comparing ISB Hyderabad with a US university is a lengthy discussion. Your choice should depend on whether you are planning to settle abroad or settle within India. If your ultimate goal is settling abroad, US universities should be your only option.

If we compare the pay structure, the average package offered at ISB Hyderabad is nearly the same as your current salary whereas US universities offer 7 times better salaries.

Both options require a lot of effort from the initial stage. To get into either, you need a spectacular profile and an impactful application strategy.
